IMPROVEMENT IN CLOTHES-WRINGERS.

Specification forming part of Letters Patent No. 140,592, dated July 8, 1873; application tiled January 3, 1873.

To all whom t may concern:

Be it known that I, CHARLES RoBrNsoN, of Boston, in the county ot' Suffolk and State of Massachusetts, have invented an Improvement in Washing and Wringing Machines; and I do hereby declare that the following is a full and exact description thereof, reference being had to the accompanying drawings making part of this specification- Figure 1 being a side view of a machine provided with my improvement as arranged for wringing clothes; Fig. 2, an end view of the same; Fig. 3, a section of a part thereof.

Like letters designate corresponding parts in all of the figures.

My invention consists in the application ot' elastic pressure-levers to the upper or counter roller ot' roller-wrin ging, or combined washing and wringing-machines, substantially as hereinafter set forth.

In the drawings, the invention is represented as applied to an improved construction of washin g and wringing rollers and bars, secured to me by previous Letters Patent; but the improvement is applicable to other rollenwringing and washing machines.

The arrangement shown in the drawings isv for wringing, which requires more .powerful elastic compression than the washing-machine arrangement. There is a lower, large, or main roller, A, of India rubber or other elastic material, which is turned by a crank, a, on its shaft or otherwise; and above this is a smaller roller or bar, B, which may be made of wood, covered with zinc or other metal. This requires to be pressed upon or against the other roller with a strong elastic force. For washing, it is suficient to place the elastic loops b b, attached to the uprights U C of the frame, over the bar or roller B; but for wringing, I now employ two pressure-levers, D D, pivoted at one end to the respective uprights, and pressed down upon the projecting ends of the bar. The movable end ofeach lever is brought down and held under an elastic stop, E, of peculiar construction. A short tube or cylindrical block, f, ot' India. rubbersay halt' an inch in diameter-is inserted in a hole, g, of the same diameter in the upright. The hole reaches two-thirds ofthe way through the upright, more or less, and the block or tube fills the same and projects far enough out of the upright to hold the lever D beneath it. Thel hole through the tube or block is large enough to receive a screw, h, which is passed through it and screwed into the upright beyond the holef therein, the head of the screiv holding the tube or block in place, and furnishing a rigid stem to resist the pressure of thel lever upward, while the elastic tube around it gives suticient yielding elasticity to the lever to serve the purpose of elastic compression in wringing.

The lever is readily removed from under or replaced beneath the elastic stop by a slight lateral movement.

The device is very cheap, simple, convenient. and effective.

What I claim as my invention, and desire t0 secure by Letters Patent, is

The pressure -levers D D and elastic stops E E, constructed and operating substantially as herein described, in combination with the bar or roller B of a wringer, for the purpose specied.

Specication signed by me this 5th day of November, 1872.
